Edit in peek definition Window!

This is the coolest thing since Spreadable Bacon. In Visual Studio 2017, you can view a method definition, and edit the code right in a pop up window with the Peek Definition command. In the screenshot below, I’m actually editing the code right in the pop up window itself. This will save you a bunch of time by not having to dig down into other folders where your classes or methods are defined, just to make a minor adjustment.
